NEEDLE FO R SELF-BINDING HARVESTING-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 691,240, dated January 14, 1902.

Application filed May 22, 1900.

To all whom it may concern.-

Be it known thatwe, BAILEY O. CAUDRY and CHARLES F.'DEPLANTY, citizens of the United States, residing at Ooifeyville, in the county of Montgomery and State of Kansas,

have invented certain new and useful Improvements in Needles for Self-Binding Harvesting-Machines, of which the following is a specification, I

Our presentinvention pertains to improvements in needles for self-bindin g harvestingmachines, the construction and advantages of which will be hereinafter pointed out, reference being had to the annexed drawings, wherein Figure 1 is a side elevation, partly in section, of so much of a needle as is necessary to a proper illustration of our invention; Fig. 2, a transverse sectional view on the line 1 1 of Fig. 1; Fig. 3, a perspective view showing one of the guide-rollers and its box in aseparated condition; and Fig. 4 a similar view of the other roller and box shown in the forward portion of the needle, Fig. 1.

The object of our invention is to provide an improved needle for binding-machines, one having roller-guidesmounted therein in such a manner that the rollers maybe readily removed and at the same time be so protected 0 as to prevent the loose endsof fiber or twine from becoming entangled therewith to the detriment of the operation ofthe device.

We are aware that it is not broadly newto provide needles of the' class herein referred to with roller-guides for the binding-twine, and no claim is made, broadly, to any such construction.

Referring to Fig. 1,A represents the needle, having at its forward end a recess or pocket,

40 which is adapted" and designed to receive roller B and'its supporting box or bearing. Upon referring to Figs. 2 and at it Will be observed that said box is composed of two sections 0 O of like shape and dimension, which 5 when brought together and put in place make a close fit with the recess in the forward end of the needle. Each of the members 0 G is provided with an opening D, adapted and designed to constitute a support or bearing for the outer ends of axle or shaft E, upon which roller B is mounted. As will be noted Serial No. 17,583.. (No model.)

die, the recess in the needle is preferably.

formed with a slight taper, so that the box or supporting member and the roller can be inserted from one side only. To hold the parts in place after they are brought to position, a spring-pin G or other suitable fastening device is passed into an opening formed by having a seat or recess out out in the needle, as well as in the members 0 O, as is best illustrated in Figs. 1 and 4. It will be seen upon reference to Fig. a that the recesses in the members O O are made with a taper in order to permit the pin after it comes to place to spring out into said tapered portion, and thus to more firmly lock the parts in position.

It is of course tobe understood that any form of locking device may be used for hold.- ing the parts in place, and We do not desire to restrict ourselves to that particular type shown and described. I

In Fig. 3 there is illustrated a form of box or bearing for the roller which is used in what may be termed the heel of the needle. It is similar throughout to that shown in Fig. 4, with the exception that the checks or guards H are so shaped as to conform to the passage of the twine at this point. Manifestly the style of these guards will vary according to the location of the guide-roll and the particular type of needle employed, and the present illustration is to be taken merely as one embodiment of our invention.

By the use of a roller properly supported and protected much friction and wear of the parts of a binder are obviated. For instance, there is not nearly so much strain placed upon the tension device nor upon the device used for holding the twine during the retrograde movement of the needle. By reason of mounting the roller in a box or bearing, such as is herein described,itwill be seen,more particularly upon reference to Fig. 2, that the and guards extending out from the box around a portion of the roller.

pin or axle E cannot become displaced,which frequently happens when the axle or support for the pin is simply passed through the body of the needle proper.

Having thus described our invention, what we claim is- 1. In combination with a binder-needle for harvesting-machines, having a recess formed therein; a sectional box or bearing detachably secured Within said recess; and a roller carried by said box.

2. In combination with a binder-needle for harvesting-machines, having a recess formed therein; a sectional box or bearing adapted to be secured within said recess; a roller carried by said box or bearing; and guards extending out around the roller at that portion Where the twine does not come into contact or pass thereover.

3. In combination with a binder-needle for harvesting-machines, having a recess formed therein; a two-part box or bearing detachably mounted within said recess; a roller interposed between the parts of said box; a pin 1 extending through the roller and said box;

4. In combination with a binder-needle for harvesting-machines, provided with a recess therein; a two-part box or bearing adapted to be mounted within said recess; a roller carried by said box; guards extending out from the box around a portion of said roller; and a spring locking device for holding the box in its position within the recess.

5. In combination with a needle for binding-machines, provided with a recess near its outer end, and with a second recess at a point in rear thereof; a groove or channelextending between said recesses; removable boxes mounted in each of said recesses; a guideroller carried by each of said boxes; and means for securing said boxes in position.

6. In a binder-needle for harvesting-machines, having a recess formed therein; a box or bearing detachably secured Within said recess; and a guide-roller carried by said box.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
